Is my friend selfish or am I just exaggerating?

[Tulloni]

Well done on the book Krzysztof! Its not an easy thing to get a book published especially with all the competition out there. I hope it sells well!

As for the friend.... hmm, its a shame you've had a falling out but these things happen. I would try and mend it but if it gets worse you may have to dump him... as a friend I mean (not a lover!). Is there a reason there's some distance between you two? Has something happened? I would question him and challenge him. Ask him to explain why he's behaving like this. If he's not interested in the book's content then that's fair enough but even so he should surely post it on Facebook as a simple favour - that's what les amis do after all!

How long have you known this friend for anyway? Are you really really close to him?

It is bad he acted like that after your wallet was stolen. Given the circumstances he should've been a bit more understanding. If he treats you like that in a time of crisis I would just forget about him there and then but it is your choice. Still if he keeps behaving like this then you might want to consider quitting him. Just don't let him mistreat you!
